/**
 * BoltPress — base blog stylesheet.
 *
 * Covers home.php (posts listing), single.php (single post),
 * archive.php (category/tag/date/author), and search.php. Starter
 * templates can ship `starter-templates/<slug>/blog.css` to fully
 * override this — those stylesheets auto-enqueue after this one via
 * BoltPress_Blog_Templates::enqueue_blog_styles().
 *
 * Rules are driven by BoltPress design-token custom properties
 * (see inc/design-system/class-css-generator.php) so that any active
 * template's palette applies out of the box without custom CSS.
